If so please reply! This is an elusive problem, as the script works fine from the remote server: sudo su - nagios [nagios@remoteserver1 libexec]$ ./check_oracle --tns $ORACLE_SID OK - reply time 0 msec from xxxxx as well it should work, since my env contains: [nagios@remoteserver1 libexec]$ env HOSTNAME=blah.domain.com SHELL=/bin/bash TERM=xterm HISTSIZE=1000 OLDPWD=/u1/apps/oracle/product/10.2.0/bin USER=nagios LS_COLORS=no=00:fi=00:di=00;34:ln=00;36:pi=40;33:so=00;35:bd=40;33;01:cd=40;33;01:or=01;05;37;41:mi=01;05;37;41:ex=00;32:*.cmd=00;32:*.exe=00;32:*.com=00;32:*.btm=00;32:*.bat=00;32:*.sh=00;32:*.csh=00;32:*.tar=00;31:*.tgz=00;31:*.arj=00;31:*.taz=00;31:*.lzh=00;31:*.zip=00;31:*.z=00;31:*.Z=00;31:*.gz=00;31:*.bz2=00;31:*.bz=00;31:*.tz=00;31:*.rpm=00;31:*.cpio=00;31:*.jpg=00;35:*.gif=00;35:*.bmp=00;35:*.xbm=00;35:*.xpm=00;35:*.png=00;35:*.tif=00;35: ORACLE_SID=DBPRD MAIL=/var/spool/mail/nagios PATH=/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/u1/apps/oracle/product/10.2.0/bin:/home/nagios/bin INPUTRC=/etc/inputrc PWD=/usr/local/nagios/libexec LANG=en_US.UTF-8 SSH_ASKPASS=/usr/libexec/openssh/gnome-ssh-askpass SHLVL=1 HOME=/home/nagios LOGNAME=nagios LESSOPEN=|/usr/bin/lesspipe.sh %s ORACLE_HOME=/u1/apps/oracle/product/10.2.0 G_BROKEN_FILENAMES=1 _=/bin/env The command is predefined in the nrpe.cfg file on the remote server as follows: command[check_ora_tns]=/usr/local/nagios/libexec/check_oracle --tns DBPRD On the nagios server I run this command: /usr/local/nagios/libexec/check_nrpe -H 10.207.9.71 -c check_ora_tns ERROR: Cannot Determine ORACLE_HOME for sid DBPRD In the beginning of the check_oracle script I added: export PATH=$PATH:/u1/apps/oracle/product/10.2.0/bin;export PATH export ORACLE_HOME=/u1/apps/oracle/product/10.2.0;export ORACLE_HOME export ORACLE_SID=BABYCPRD;export ORACLE_SID ORACLE_BASE=/u1/apps/oracle What am I doing wrong??? </body> </html>
